Regional rivals Saudi Arabia and Iran traded accusations Tuesday over the escalating conflict in Yemen, which the UN rights chief warned was on the brink of "total collapse". In the heaviest raids yet of the six-day Saudi-led air war against Shiite Huthi rebels, explosions lit up the skies over Sanaa on Monday night and rocked other parts of the country on Tuesday. Amnesty International accused the Saudi-led coalition of "turning a blind eye to civilian deaths" as it reported four children were among six burned to death in strikes on Ibb, in central Yemen. The UN children's fund said that at least 62 children had been killed and 30 injured during the fighting in Yemen over the past week.
